Application filed Deeember 24, 1927. Seiial N0. 242,393.

My invention, relates to devices which are readily applicable to ordinary window frames to control draft, or ventilation of the room.

An important oloj ect is 130 provide such devices of simple and economical form, and which may, therefore, be sold at W price to hous eholders or others, for ready installation by them, and easily. rernoved, without 10 injnryv to tl1e window structure.

A further object is to provide improved structural and operative features in ventilating appliances of this dass, regardless of cost.

T0 roalize the stated and other objects, tl1e invention Consists, as'e1nb0died in one representative form, of generally-triangular end members or plates having formations readily applicable in the sash-channels of the Win- 2 dow frame, and other, diagonal formations 130 ret'zeive retaining o1 clamping members in which l1e Wind baffling or draft regulating device is inserted, Such device consisting of wire screening o1 textile fabric in a suitable adjustable or non-adjustable fra1ne, or an imperforace slieet of suitable material such as 'glass 01 fibre, cardboard, eto.', of suit-able character. The opposite and members and the aforesaid diagonal formations amrelated to one another' to locate the bottom edge portion of the baffle exteriorly of and Preferably in contact with t he outer edge of the inner sill, and within the usual recess in the window frame forwardly of the inner sill.

Preferably each and piece is fornied from a blank of flat sheetmetal, cut to proper shape and Pressed or bent to final form, and the clant1ping 01 retaining devices insercable in the diagonally arranged channel formations 40 of the and plates are also desirably of pressed sheet metzil.

The charateristic's and advantages of the invention are further sufiiciently explained in connection with the following detail description of the accompanying drawings, which ill'ustrateTepresentative embdiments. After considering .these examples, skilled *persons Will understand that many variations maybe made without departing from the prineiples involved, and wo contemplate the employment 015 any structures that are properly witl1in the scope of the appended claims.

Fig. 9 is a top plan of the same, in opera twe position. Re ferring first to the embOdirnent shown 1n F1gs. 1 to 6: Fig. 6 shows a blank B properly shaped for bending 130 produce orie of che end members E of Fig. 4. 'The blank 1ncludes a generally triangular portion or plate 1 having a top edg 2, a vertical side edge and a diagonal side edge 4, the last named 6dge being jointed at the apex 5 of the triangular plate portion. The portions of the integral blank are shown by dotted lines which indicate fold or bending lines. Strips 6 and 7 are arranged consecutively byond oho diagonal edge 4, being the same length as t hat edge. Next to strip 7 is a Strip 8 hav1ng a diagonal lower edge 9. Successively next so strip 8 are strips 10 and 11 of lengths equal t o the greatest length of strip 8. Connected successively to the vertical edge 8 are strips 12, 13.

Strip 11 has and flapS 14 and 15. Strip 8 has an end flap 16. Strip 12 has aininner side flap 17. Plato portion 1 has a top flap 18 along its edge 2. Strip 13 has als its upper and a fastening prong 19. The blank is folded by any suitable method or mechanism so the form show1i in Figs. 3 and 4, where it Will be .observed that the strips 12 and 13 are bent produoe a formation of L shape fitting in the sash chani1el C brought ver 1Jhe fiap 17 of strip 12 and these portions are secured together by Welding, soldering or otherwise. The endpiece is .put in position as best shown in Figs. l, 2, and 3, with its lowei end resting 0nthe window sill S and With theL formatio'n 12, 13 loeated as abovestated, and is secured by driving the p0int 0r prong 19 int0 alle side frame meinber, this prong being bent a1; a riglit angle 130 the strip 19.

Any suitable window screen o1 bafile 1nay be inserted in 1;he diagonal ehanr1els 01 the end members( It is -preferred, however, t0 provide channel strips 01 clamping strips 30, Fig. Which a1e bent up fronia' flat sheet Ine1;al including abase strip 31, side strips 32 slightlyc0nvergent,and end strips 33 which are turned inwardly. A clamping strip is appliedtoeach end ofany suitable 'screen 01 bafile suchasK, Fig. 1, this beinga window screen of the collapsible Cype including a fian16 supporting wiremeshor other fabric.

. 'Ihe clamping strips are plac(edabout the end ffame members andthe free ends 01 strips 32 are then yieldably bendable 130 engage 1zhe strips 33 within the inward edges 01 the f1*ame members. The ballle strips W113h the .frame in place are then puslied d0wn int0 the upper ende 0f the diagonal-channel f01= mations 0f 1zhe end membersuntil the baiile is located asho-wn in Fig. 1 anal 2, and particularly 130 locate the lower edge portion of the bafi1e K Within the usual recess in the window-frame forwardly of 'the inner sill S,

min and dust, subject to the force 0f Wind,

is prevented from entering within the window opening under thebaflle.

'Instiaad of abaflie 01 sereen ofthe type described a sheet of any suitable imperforate material may be inserted in the cla1nping strips 32 and by their agency retained in the end members. F or example, heavy paper 01 cardlooard may loe employed for this purpo-se and when so used the elamping flanges 33 Will properly engage 1he opposite faces of the baflle sheet and Will properly adapt themselves 150 its thickness and properly hold the ba1lle in position in 1;he end members. Fig. 7 shows such a solid baffle sheet 0r board W in operative position. Baflies of 13hi s thara0- ter may be supplied Wi1;h any suitable Hat 01 embossed surface decorations such as D, 130 add 130 the decorative appearance 0f the room in which 1;l1e appliances are used. Such solid bailies are windproof, and completely deflect the entering air, and they may also be water-proof o1 treated onthe outer face With any suitable water-proofing material, 130 render them i1npervious t0 entering meistule, ahd ab the sahne time prevent nisture beingblown int0 tl1e ro0m.

Figs. 8 and 9 show a modification, principally in thesheet metal end member E This consists 015 a central portion or triangular plate1 similar to1zhe previous eX-ample, provided at itsinner eclge with integral, an gularly-bent strips 12,13 producing an L- shaped formation 130 fit in the sash channel, also as in the previous example. Ab its outer, diagonal edge the platehas asingle integral strip or flange 40 bent a1: aright angle and having an overturnedandpressed margin 41 to provide a smooth, iounded ed'g'e 42. T0 cooperate with this flange ehe plate is previded'with flexible orresilient clips 44 cons1stii1g 015 pieCes o'f tlie plate material punched out' anclbent to thep0sitions showi1, substantially parallel to flange 40. The
